The Nabataeans, like many other ancient peoples, revered the sun as a source of light and life, and Petra's design reflects that reverence. Many of the city's most sacred spaces are designed to correspond to solar patterns, such as solstices. This meticulous design provides modern scientists and archaeologists with valuable insight into what the Nabataeans valued and how unique Petra must have been.

Wyoming Territory became the first state to grant the right to vote to women above the age of 21 in 1869. Historians believe that, in addition to granting women equal rights with males, MPs passed the statute in order to attract more settlers to the state.

The Swedish people are big recyclers. Only 1% of garbage is thrown away, with 50% recycled or composted and 49% burnt for electricity. This may sound like good news, but it has resulted in one major issue: there isn't enough rubbish to keep the incinerators going. As a result, Sweden has devised an innovative solution. To keep the lights on, they import garbage from Norway and the United Kingdom. As an added plus, the nations actually pay Sweden to remove their rubbish!

The massive red walls of Jaigarh Fort can be seen from almost anywhere in Amer. Keeping in mind that I had not yet seen Kumbhalgarh Fort, these walls appeared interminable. The guard assured us they were just 3 kilometers long, but they looked much longer. The brilliant red hue set them apart from what we observed at Amer Fort. Personally, I enjoyed visiting the turrets, climbing up the narrow open staircases to see what was below, and simply roaming about the fort's perimeter.

Vatican City is most likely the only country on the planet without a prison. The country does have a few pre-trial detention facilities. According to the Lateran Treaty, those convicted and sentenced to jail serve their time in Italian prisons. The Vatican government pays for the costs of incarceration.

The theories of Einstein describe how massive objects distort space-time. According to Einstein, the movement of these objects should cause ripples in the fabric of space itself. In fact, three Nobel Laureates were able to observe a collision between two black holes 1.8 billion light-years apart. One of these black holes is 31 times the mass of our sun, while the other is 25 times. In a fraction of a second, the collision converted the mass of approximately three suns into gravitational wave energy!

Large ivory tusks on the narwhal dolphin, which resemble unicorn horns, are frequently stolen. The Greenland Sea and Baffin Bay are home to the only surviving populations

That quantity may appear to be very astonishing at first, but keep in mind that the moon does not create its own light; rather, it reflects the light of the sun. And not particularly well. "The brightness of the Moon depends on the exact angle between the Earth, Moon, and Sun... the brightness of a Full Moon is typically reported as a magnitude around -13, roughly 14 magnitudes or 400,000 times fainter than the Sun," according to Sky & Telescope. That implies the moon has a lot of work ahead of it if it wants to be as visible as our brightest star.

Let us explain why you should have an eye test before you book one. A butterfly's wings are covered in thousands upon thousands of tiny scales. And the hues you see as a butterfly flies through your yard are the reflection of different colors through the scales. The wings themselves are constructed of chitin, which is the same protein that makes up an insect's exoskeleton. Chitin, like an exoskeleton, is translucent. You've already learned something new!

A Bloodhound's sense of scent is so acute and exact that it may be used as evidence in court. Their scent membranes allow dogs to distinguish odours at least a thousand times better than humans. Bloodhounds are frequently employed to locate missing people and criminals. They can follow traces that are almost 300 hours old and can go 130 miles on a path.

I saw a number of Irish bars when walking around Old Quebec. I even snapped the photo below in front of one of them. So I conducted some research and discovered, thanks to Travel & Leisure, that I was on to something. In fact, there is a sizable Irish community in Quebec. During the 17th century, French Irish were transported to Quebec to help populate the province. Historians believe that around 40% of Quebec's population is of Irish heritage.

There are several historical highlights at Niagara Falls. One of the oldest United States flags still in existence, seized by the British during the War of 1812, is on display at Old Fort Niagara. Lewiston was the site of the opening fight of the War of 1812 and the final terminus for the Underground Railroad, a network of hidden passageways for escaping slaves. The original Flight of Five Locks, a mechanism for elevating and lowering boats, was completed in 1815 and is still operational on the Erie Canal near Lockport, giving the largest lift in the shortest distance on all U.S.-made canals.

The city got its name from the Hindi word khaujur, which means "date," since the city walls were covered in date palms. Khajuraho was known as Khajjurpura in ancient times.

Koreans frequently utilized shared pronouns such as "we" or "us" rather than "me" or "I." This stems from Korean culture and society's communal nature. Learning how and when to apply the distinction is a delicate nuance that takes years to grasp for outsiders.

Trifasciata is a member of the succulent family but is not a cactus. Its look often leads people to mistake it for a cactus. The plant has thick, fleshy leaves that mimic those of a cactus. In actuality, agave, jade, and aloe vera plants share a structure with snake plants. The plant's maintenance needs are likewise quite similar to those of cacti.
